Notes

※1 Even if the file extension matches, files containing only audio without any visual content (video or animation) cannot be registered.

※2 Videos with the "AV1" codec cannot be registered.

  • Even if the restrictions are met, Upload may not be possible depending on how the video was created or edited.
    If you are preparing a large number of images or videos, or paid content, please prepare a sample video in advance and verify that it can be registered and edited as intended.
  • Depending on the length and size of the video and your usage environment, you may need to wait a long time for processing to complete.
    If processing does not finish after an extended period, please consider canceling the process once, shortening the original video, and then re-registering it.

※3 When semi-automatically generating from a video already registered to a cover or Step, the file can be used regardless of the original video's file extension.

※4 If the amount of dialogue or activity is large, an error may occur even with videos that meet this limit.
Please delete unnecessary sections or split the video into segments of approximately 10 to 20 minutes.
